The Genuine Husqvarna 577975201 Outer Spike (also known as a felling dog or bumper spike) is an essential professional upgrade or replacement for your 562 XP series chainsaw. This outer spike attaches to the clutch cover, working in tandem with the inner spike to provide a dual-point pivot for more stable, controlled bucking and felling of large timber.
By adding or replacing the outer bumper spike, you increase the saw's "bite" into the wood. This significantly reduces operator fatigue by allowing the engine's torque to do the work while the spikes maintain a secure anchor point. Crafted from high-strength hardened steel, this OEM component is designed to withstand the heavy leverage of professional logging.
